Midterm concept and outline.

Initial concept

I initially wanted to make a top-down shooter game, I designed a lot of stuff, a collision algorithm for the bullets, obstacles, and enemies, a multitude of weapons with special traits, power ups, an infinitely-expanding map, and a bunch of other interactive elements. I got really frustrated with the implementation and gave up on the idea. I came back a day later and didn’t know whether I should abandon the game or not, so I changed to code to make it a horizontal shooter game,and  below is where i reached, before completetly abandoning the idea, even though I had almost all the logic and algorithms implemented, I just couldn’t work with a project a didn’t love.

Hence the delay of submitting this assignment. 

Current concept

I woke up 2 days after, I saw a spider on top in some corner no one goes to in my house with a small net. I decided it to befriend it and I called it Webster.

This sparked an idea in me, which is to make a game of a spider swinging around the world with a web. Then I drew my initial concept.

The most frightening part

This would probably be the implementation of gravity and the physics of the web/rope. I already implemented them though.

class Spider {
  constructor(x, y) {
    // store position & velocity in p5 vectors
    this.pos = createVector(x, y);
    this.vel = createVector(0, 0);
    // spider radius = 15 is used for collisions
    this.radius = 15;
    // track if spider is attached to rope or not
    this.attached = false;
  }

  update() {
    // apply gravity each frame
    this.vel.add(gravity);

    // if spider is attached, we do some rope physics
    if (this.attached && ropeAnchor) {
      // figure out how far spider is from anchor
      let ropeVec = p5.Vector.sub(ropeAnchor, this.pos);
      let distance = ropeVec.mag();

      // only if rope is stretched beyond rest length do we apply the spring force
      if (distance > ropeRestLength) {
        let stretch = distance - ropeRestLength;
        // hooke's law, f = k * x
        let force = ropeVec.normalize().mult(stretch * ropeK);
        // add that force to our velocity
        this.vel.add(force);
      }
    }

    // apply damping (which is basically air resistance)
    this.vel.mult(damping);

    // move spider according to velocity
    this.pos.add(this.vel);
  }

  show() {
    // draw the spider sprite instead of a circle
    push();
    imageMode(CENTER);
    image(spiderImg, this.pos.x, this.pos.y, this.radius * 2, this.radius * 2);
    pop();
  }
}
